Yoshi doesn't wear a hat whereas zelda wears a green hat unless he is playing dress up in which case he likes to cosplay as mario in a red hat or sanic in a blue hat. His other hobbies include shoving carrot's up horses arses presumably to sexually pleasure them and make their owner Luigi mad and ruin the kingdoms economy by using alchemy to turn grass into gems.
